PACKING RING.

Application fiIedMarehZO, 1924." SerialNo. 700,738.

To all whom it may concern Be it known that I, JULES A. LE BLANo, a citizen of the United States, residing at Port Arthur, in the county of Jefferson. and State of Texas, have invented certain new and useful Improvements in Packing Rings, of which the following is a specification.

This invention relates to new and useful improvements in packing rings which are especially adapted for use in pumps or the like wherein gasoline or kerosene or any other liquid is used, and further adapted to be used on packing rods.

One of the important objects of the invention is to provide a packing ringwhich is formed of tupelo root. This tree from which the packing ring is formed grows in the swamps and low lands of North America,'and thewood taken from these trees when in use as a packing ring will not absorb the liquid as is the case with the other wooden or fibrous packing rings now in use.

'A further object of the invention is to provide a packing ring of the above mentioned character, wherein the same is provided with a casing which extends entirely around the ring the outer wall of the casing being of a greater thickness than the other walls thereof.

A further object of the invention is to provide a packing ring of the above mentioned character, which is simple in construction, inexpensive, strong and durable and further well adapted for the purposes'for Which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same,

Figure l is a plan view of the packing ring embedded in the casing,

Figure 2 is a side elevation thereof partly in section,

Figure 3 is atop plan view of a packing ring formed of tupelo root without having a casing extending therearound,

Figure 4 is a vertical section therethrough, and

Figure 5 is a fragmentary detail view of a modification showing the manner in which the packing ring is split.

In the drawing wherein for the purpose of illustration is shown the preferred emasbestos or the like,

bodiment of my invention, the numeral 1 designates a packing ring which is made from tupelo root which is obtained from the trees growing in the swamps and low lands of North America. The packing ring is substantially rectangular in cross section as clearly SllOWIl lIl F igure 2 of the drawing, and adapted to extend entirely around the packing ring is the casing 2 which may be of any suitable material such as rubber, and I do not wish to limit myself to the particular kind of material to be used; As is further noted from Figure 2 of the drawing, the outer peripheral wall of the casing is of a thickness greater than the thickness of the other walls of the casing, and the purpose of this construction is to provide a packing casing which will be strong and durable. A packing ring of the above mentioned character is especially adapted for use upon packing rods on hot liquid pumps and will be very efiicient in its operation. By using a packing ring formed of wood such as the tupelo root the same will not be subject to absorption and this will render the packin ring .very efficient in its operation and will prolong the durability of the same.

In Figures 3 and 4 of the drawing, a packingring formed of tupelo root is shown and is illustrated by the numeral 3, and the same is split as at 4. In using a packing ring of the character shown in Figures 3 and 4 of the drawing, the use of a casing therefor is not necessary and a packing ring of this type is especially adapted for use in packing the fluid end of a pump for use in pumping hot liquids such as gasoline or kerosene. This packing ring is also substantially rectangular in cross section as is illustrated at 5 in the drawing.

In Figure 5 of the drawing the packing ring is divided or split on a bias as is illustrated at 6 and this construction permits the cutting away of the respective ends of the split ring to the proper size. Any suitable means may be provided for reducing the size of the packing ring such as by employing a sharp knife, a file or the use of an emery wheel, and I do not wish to limit myself to the particular manner in which the respective ends of the ring are cut away.

It will thus be seen from the foregoing description, that a packing ring has been provided which is very economical and is constructed of such material as to be strong and durable and will resist absorption of the invention and the scope of the appended liquids in which the packing ring is supclaim.

LE BLANC.
